Abstract

Abstract A transparent telephony system is disclosed for providing hands-free communication. The transparent telephony system includes a device for initiating a call between a caller's location and a call destination based on a voice utterance (e.g., the call recipient's name) made by the caller, a device for reproducing the voice utterance made by the caller at the call destination so that the call recipient may identify the caller, and a device for handling the call attempt in accordance with a voice utterance made by the call recipient. The call handling device enables the call recipient to optionally accept the initiated call and establish two-way voice communication with the caller by uttering an appropriate voice command ( e.g., "go-ahead" or "yes"). Further, the system provides telecommunications between parties that seems "transparent" with respect to the actual communication network involved, partly since the caller's voice command initiating the call and the call recipient's acceptance utterance are forwarded and heard by the respective parties as if they are initiating a normal conversation with one another in the same room or location.
